HDMI display doesn't work after update

VIM3
1

Hi all, I recently updated my VIM3 to the latest kernel and my HDMI display is black on reboot (but I can still SSH into my VIM3). I hooked up a Serial cable to see what the output it and I find these lines:

khadas_support_mode 1920x1200p60hz
bestmode is 1920x1200p60hz, IEEEOUI 0x000c03
HDMI Mode
lcd: error: outputmode[1920x1200p60hz] is not support
[…]
cvbs: outputmode[1920x1200p60hz] is invalid
hdmitx: outputmode[1920x1200p60hz] is invalid
lcd: error: outputmode[1920x1200p60hz] is not support

It seems like the native resolution of my screen is not supported anymore. Does anyone know how to either:
A) change the default resolution to one that is supported by the VIM3
or
B) have 1920x1200 be supported by the VIM3?

Best regards,
Matthieu.

Does the screen works before update?

Can you try to disable the HDMI resolution autodetection? Edit /boot/env.txt to change hdmi_autodetect=yes to hdmi_autodetect=no.

I don’t have screen with resolution 1920x1200， so I’m not sure. Do you have other screen to test.

Yes, the screen worked before the update.
I also followed your advice and set hdmi_autodetect=no and then hdmi=1080p60 and it works now.

Thank you!
